problem 1: links to blocks permissions changes were missing in boost
problem 2: when modifying link from dashboard user is returned to profile ('returnurl' passed but not respected)
problem 3: link to check permissions missing from category management page
fix: instead of respecting both 'return' and 'returnurl' parameter use only 'returnurl'
fix: use 'popup' layout when modifying permissions for a block
* Implemented a new course and category management page.
* Deprecated the old management interface.
* Unit tests to cover the new API and core functions.
* Behat tests to cover the new interface.
- fixed user styles in base theme
- added new divs for better control on user profile and user index pages
- reduced data on course user profiles down to minimum
- removed user/tabs.php completely and all uses of it
- changed default user icon pix to something very bland (bye bye smiley cake)
